Answer:

The theoretical probability of landing on orange is one fourth, and the experimental probability is 20%.

Step-by-step explanation:

Since the 4 sections are equal, theoretical probability is given by:

p = 1/4

Out of 20 trials, 4 resulted in pink, hence experimental probability is given by:

p = 4/20 = 0.2 = 20%.

Hence,

The theoretical probability of landing on orange is one fourth, and the experimental probability is 20%.

Answer:

DB = 15

Step-by-step explanation:

∠ C and ∠ D are the base angles of Δ BCD

since they are congruent , that is ∠ D = ∠ C

Then the triangle is isosceles with the legs being congruent, so

DB = BC = 15

Average There are 120 ways to choose the three positions so that at least one freshman and one sophomore is chosen.

There are a total of 4 possible combinations of freshman and sophomore for the three positions, with at least one of each:

1. Freshman President, Sophomore Vice-President, Sophomore Treasurer

2. Sophomore President, Freshman Vice-President, Sophomore Treasurer

3. Freshman President, Sophomore Vice-President, Freshman Treasurer

4. Sophomore President, Freshman Vice-President, Freshman Treasurer

For each of the four combinations, there are 10 possible ways to choose the specific freshmen and sophomores for the positions (5 freshmen and 5 sophomores). That means there are 40 possible ways to choose the three positions with at least one freshman and one sophomore. Multiplying this by the 3 possible orders of the positions (President-Vice-President-Treasurer, President-Treasurer-Vice-President, Vice-President-President-Treasurer) gives us a total of 120 possible ways to choose the three positions so that at least one freshman and one sophomore is chosen.

The solution of the given differential equation is

x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0

The given differential equation can be written as

ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|

To solve this equation, we will use separation of variables. This means that we need to separate the terms containing 'x' and the terms containing 'y' on different sides of the equation.

We can rearrange the equation as,

ln x * (dx/dy) - [(y+1)/x]^2[(y^2)/2] - 2y - ln|y| = 0

Now, let us separate the terms containing 'x' from terms containing 'y':

ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|

On one side of the equation, we have ln x * (dx/dy) and on the other side, we have [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|.

Now, we can integrate both sides of the equation with respect to 'y':

∫ ln x * (dx/dy) dy = ∫ [(y+1)/x]^2[(y^2)/2] + 2y + ln|y| dy

Integrating both sides of the equation, we get

x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0

where c is a constant of integration.

Therefore, the solution of the given differential equation is

x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0

Applying the definition o a supplement of an angle, the measure of angle P in degrees is: 105°.

The supplement of an angle is defined as the angle measure that is added to the angle to give a sum of 180 degrees.

For example, the supplement of angle X is 180 - measure of angle X.

Given the following:

Supplement of angle P = 180 - measure of angle P

Measure of angle P = (180 - measure of angle P) + 30 degrees

Therefore:

(180 - m<P) + [(180 - m<P) + 30] = 180

Open the parentheses:

180 - m<P + 180 - m<P + 30 = 180

Combine like terms:

390 - 2(m<P) = 180

390 - 180 = 2(m<P)

210 = 2(m<P)

210/2 = 2(m<P)/2

105 = m<P

Answer:

To find the angle subtended by a chord at the center of a circle, we can use the formula:

θ = 2 * arcsin (c / 2r)

where θ is the angle subtended by the chord, c is the length of the chord, and r is the radius of the circle.

Step 1: Substitute the given values into the formula

θ = 2 * arcsin (13.2 / (2 * 9.4))

Step 2: Simplify the equation

θ = 2 * arcsin (13.2 / 18.8)

Step 3: Use a calculator or a math table to find the value of arcsin

arcsin (13.2 / 18.8) = 0.636 radians

Step 4: Multiply the value obtained by 2

0.636 * 2 = 1.27 radians

Final Answer: The angle subtended by the chord at the centre of the circle is 1.27 radians or 72.8 degrees

An absolute value equation can have two solutions, one for the positive case and one for the negative case. It's important to check both cases to make sure that we have found all of the solutions to the equation.

An absolute value equation is an equation that contains an absolute value function. The absolute value of a number is defined as the distance of that number from zero on the number line. It is always non-negative.

When solving an absolute value equation, we need to consider two cases: the case where the value inside the absolute value sign is positive, and the case where it is negative.

For example, if we have the equation |x| = 2, we can solve it by first considering the case where x is positive:

x = 2 (because the distance from zero is 2 on the positive side of the number line)

Alternatively, we can consider the case where x is negative:

x = -2 (because the distance from zero is 2 on the negative side of the number line)

So in this example, there are two solutions: x = 2 or x = -2.

The probability of getting a total value of $50 is 1/6.

There are three possible outcomes for Ben's prize: $5, $10, or $20.

There are two possible outcomes for Jamie's prize: $30 or $40.

Therefore, there are 3 x 2 = 6 total possible outcomes for the combined value of their prizes.

To find the probability that the total value of their prizes is exactly $50, we need to find the number of outcomes that result in a total value of $50, and divide that by the total number of possible outcomes.

The only way to get a total value of exactly $50 is that Ben wins $20 and Jamie wins $30. This is only one combination out of 6 possible combinations. So the probability of getting a total value of $50 is 1/6 or approximately 0.166.

Therefore , the solution of the given problem of triangle comes out to be Area = 2700 cm square .

An triangle is a polygon since it has four or more parts. It is a simple geometric shape. A square having angles A, B, and C is referred to as a triangle ABC. When the sides are not collinear, Euclidean geometry generates a single plane and square. If a triangle has three sides and three corners, it is a polygon.

The angles in a triangle are less than 90 degrees, the triangle is acute, greater than 90 degrees, the triangle is obtuse, and exactly 90 degrees, the triangle is a right triangle.

What is the converse of the Pythagorean theorem?

The converse of the Pythagorean theorem states that if the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle.

To determine if a triangle is acute, obtuse, or right, we can use the following:

If all the angles in a triangle are less than 90 degrees, the triangle is acute.

If one angle in a triangle is greater than 90 degrees, the triangle is obtuse.

If one angle in a triangle is exactly 90 degrees, the triangle is a right triangle, using the converse of the Pythagorean theorem, c² = a² + b².

Hence, the angles in a triangle are less than 90 degrees, the triangle is acute, greater than 90 degrees, the triangle is obtuse, and exactly 90 degrees, the triangle is a right triangle.

Since there are only single women and married men with their wives at the party, we know that the sum of the fractions of single women and married men and their wives must be 1.

(2/5) + (1-x) = 1

The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).

The area of a triangle can be found using the Heron's formula if we know the lengths of all three sides, or using the formula (1/2) * x * y if we know the lengths of two legs and the triangle is a right triangle.

In the case where the legs of the triangle are x and y long, if we don't know if the triangle is a right triangle, we can't use the formula (1/2) * x * y. However, we can use Heron's formula to calculate the area. Heron's formula states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c), where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.

In this case, since we know the lengths of the two legs x and y, we can find the area of the triangle using Heron's formula as follows:

s = (x + y + c)/2

Area = sqrt(s(s-x)(s-y)(s-c))

Where c is the length of the hypotenuse of the triangle, this information is not provided, so we cannot calculate the area of the triangle.

Therefore, The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).
